JOSEPH KELLER, OF LONG ISLAND CITY, NEW YORK.

WINDOW-BASH LIFT AND FASTENER.

Specification of Letters Patent.

Application filed March 7, 1908.

Patented Dec. 8, 1908.

Serial No. 419,748.

To all whom it may concern:

Be it known that I, JOSEPH KELLER, a citizen of the United States, residing at Long Island City, in .the county of Queens and State of New York, have invented a new and use ful Improvement in Window-Sash Lifts and Fasteners, of which the following is a specification.

This invention relates to a device for lifting and lowering window sashes and also for locking said sashes in their adjusted position, so that they can not be opened or closed. except from the inner side.

The invention consists ofthe novel features of construction hereinafter described, pointed out in the claims, and shown in the accompanying drawings, in which Figure 1 is a side elevation of a window showing my invention applied thereto, the parts arranged within the window frame being shown in dotted lines. Fig. 2 is a vertical section through a portion of a window frame or casing, showing my device in position and partly in section, portions of window sashes eing shown in side elevation. Fig. 3 is a section on the line 3-3 of Fig. 2. Fig. 4 is an enlarged side elevation of those parts upon the exterior of the window frame. Fig. 5 is a vertical section taken centrally through a metal casing set in the window frame, portions of which are also shown in section. Figs. 6 and 7 are detail perspective views of a locking mechanism.

In these drawings 1 represents a window frame, 2 the lower sash and 3 the upper sash. Within the window frame and ad acent the lower sash, preferably midway the to and bottom of said sash when it is in close position, is inserted a metal casing 4. A shaft 5 is journaled in this casing and carries upon its outer end a handle 5. A sleeve 6 is rotatably mounted upon a portion of this shaft and also projects from the casing and carries at its outer end an operating handle 6. A double drum 7 is fixed upon the sleeve 6 and a drum 8 is fixed upon the shaft 5. The sleeve 6 carries at its inner end a ratchet 9 and the shaft 5 carries a ratchet 10. There is also journaled in the casing above the shaft 5 a rock shaft 11 which carries a awl l1 engaging the ratchet 10, said pawl eing angled as shown in Figs. 4 and 7, and the rock shaft 11 also carries a depending spring 12 provided with a spur 12 adapted to be brought into engagement with the teeth of the ratchet 10 when the shaft 11 is rocked so as to lift the pawl 11 out of engagement with the ratchet 10, the spring 12 thereby acting as a brake. A hollow rock shaft 14 is mounted upon a portion of the rock shaft 11 and is provided also with an angled pawl 15 engaging the ratchet 9 and a spring 9* acting as a brake for said. ratchet, the pawl 15 and spring 9 being duplicates of the same parts carried by the rock shaft 11. At its outer end the rock shaft 11 carries a lever 13 operated by pull cord 13, and the hollow rock shaft 14 carries a lever 15 operated by the pull cord 15*.

In the window frame which is suitably cut out are mounted pulleys 16 and 17 adjacent the top of the lower sash and a pulley. 18 adjacent the bottom of the upper sash. A cable 16 is secured to the lower sash near its lower end and runs upwardly in the manner of a window cord and over the pulley 16 and is secured to and winds upon a portion of the drum 7. A cable 17 a is connected to the sash 1 adjacent its top and is oppositely secured to the cable 16 upon the other portion of the drum 7. A cable 18 is secured to the bottom of the lower sash and runs over the pulley 18 and is secured to the drum 8.

It will be obvious that the rotating of the drum 7 in one direction will wind the cable 16 upon said drum at the same time permitting the unwinding of the cable 17 and the lower sash will therefore be lifted. Upon reverse rotation of the handle 6 the sleeve 6 will be rotated in the opposite direction and the cable 17" will be wound upon the drum thus lowering the shaft. Rotation of the handle 5* will rotate the shaft 5, the drum 8 and will raise the top sash from lower to closed position, the sash being lowered in the usual manner. In order to operate these handles it will be necessary to release the ratchet carried by the shaft to be operated by drawing downwardly upon the proper cord 13 or 15 thus releasing the pawl engaging said ratchet,,and this will also bring the spring brake into operative position, the object of said springs being to downward movement 0 either of the sashes. It will also be obvious that the windows having been adjusted they will be locked in their adjusted position by engagement of the pawls with the ratchets and can not be moved either up or down without first drawing upon the proper cord to release the pawl locking the sash to be moved. In a case of heavy sashes the ordinary window weights may be prevent a too rapid employed at the side opposite that to which the above described attachment is placed.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is 1. The combination with upper and lower window sashes and a window frame, of a casing fitting within the frame, a shaft journaled therein, a handle on the outer end of the shaft, a sleeve journaled upon said shaft, a handle upon the outer end of the sleeve, a double drum fixed upon said sleeve, a drum fixed upon the shaft, a cable running over the last mentioned drum and secured to the upper sash, and cables oppositely connected to the double drum and also secured respectively to upper and lower portions of the lower sash.

2. In a device of the kind described a shaft, a handle thereon, a drum thereon, a ratchet thereon, a sleeve mounted on said shaft, a handle carried by the sleeve, a double drum carried by the sleeve, a ratchet carried by the sleeve, a rock shaft, a pawl carried by said rock shaft engaging the ratchet of the first mentioned shaft, an operating lever for said shaft, a sleeve mounted on said shaft, a pawl carried by said sleeve and engaging the ratchet of the first mentioned sleeve, a lever on said second mentioned sleeve, a cable secured to the lower portion of an upper sash and running over the drum of the first mentioned shaft, a cable secured to the upper portion of the lower sash and fixed to and-winding upon the double drum, a cable secured to the lower portion of the lower sash and secured to said double drum, said last mentioned cable winding upon the drum while the second mentioned cable unwinds, and idle pulleys guiding said cables, as and for the purpose set forth.
